SWITCH-FITTING FOR PNEUMATlC-DESPATCH-IUBE SYSTEMS.

`SIEECIFJIGATION' forming part of v:Letters Patent No. 727,138, datedMay 5, 1903.

Application led January 8, 1903. Serial No. 138,241. (No model.)

To a/ZZ whont t may concern,.-

Be it known that I, HENRY J. HEBT, a citizen of the United States,residing at Indianapolis, in the county of' Marion and State of Indiana,have invented certain new and useful Improvements in Switch Fittings forPneumatic-Despatch-Tube Systems, of which the following is aspecification.

The object of my invention is toprovide an automatically operated cutout and switch mechanism for pneumatic-despatch-tube systems, to providea special form of car to be used in conjunction therewith, to providemeans operated by the switch mechanism for preventing aclosely-succeeding car from following in the path of the rst car, and toprovide such improvements in details of construction as may hereinafterbe pointed out.Vv

The accompanying` drawings illustrate my invention.

Figure 1 is a vertical section; Fig. 2, a transverse section on line 2 2of Fig. 1.

In the drawings, indicates a fitting in which is formed a main orstraight passage 11, from which leads a discharge-passage 12. Mounted atthe point of junction of the .two

passages 11 and 12 is a switch 13, lsecured at its forward end to shaft14-that is to say, Y

the rear or free end of the switch projects in' that direction fromwhich the cars 15 come.

Formed in tting 10 above the main passage 1l is a chamber 16, in whichis mounted a transverse shaft 17, to which is secured a pair.

of arms 18 and 19, both of which lie Within the chamber 16. Pivoted toarm 18 is one end of a latch 20, which has a toe 21 normally projectinginto the line of passage 11, said toe carrying, if desired, afriction-roller 22. Latch 2O also carries a roller 23, which rests upona cam incline 24, carried by a guideplate 25, pivoted at 26 withinchamber 16. The free end of guide-plate is held adjustable by means of ascrew 27 passing through slot 28, the free end of guide 25 beingadjustable to and from passage 11. ries asupplemental guide incline 29,beneath which the tip 30 of latch 2O may pass so soon as roller 23 isforced up incline 24.

Secured'to the shaft 17 outside of the casing is an arm 31, (shown indotted lines,) which is connected by a link 32 with an arm 33, securedto the other end of the shaft 14.

Aoutlet 12.

tion.

Guide 25 car- Pivoted to arm 19 is one end of a link 34, the oppositeend of which is pivoted to a plunger 35, movable ina guide 36;substantially parallel to the axis of passage 1l. Plunger 35 is providedat its opposite end` with an inclined cam-face 37, engaged by't-he innerend of the plunger 38,-rnou`nted in a guide 39, substantially at, say,forty-jive degrees to the axis of caps, if desired.

In operation-a car being projected through passage-'11 in the directionindicated, with its end 43 foremost, comes into engagement with theroller 22 and forces the latch 2O to the rear, tip 30 catching beneaththe supplemental guide 29 and roller 23 rolling up incline 24 togradually withdraw-roller 22 from engagement with head 43. This forwardmovement of the latch 20swings arm 18 and shaft 17, so that through arm31, link 32, and arm 33 switch 13-is thrown upward to the position shownin dotted lines in Fig. 1, this taking place before'the car can passroller 22, so that the car comes into engagement with the switch 13 andis deiiected by it through the discharge- Thedescribed movement of theshaft 17 swings arm 19 so as to throw plunger 35 to thefposition shownin dotted lines in Fig. 1, thereby projecting plunger 38 into thepassage 11 to serve as a detainer for an immediately-succeeding car. Assoon as the car has passed 'through the outlet 12 spring 41 serves toreturn the parts to normal posi- If car 15be introduced into the passage11 with its head 42 foremost, said head when Vit engages roller 22serves merely toswing latch 20 about its pivotal connection with arm 18,tip 30 swinging free from the supplemental guide 29,v and the car passesthrough the main passage 11.

It will be readily understood that instead of the double-headed carshown I may use two sets of cars, both ends of one set being blunt andcapable of operating the switch,

ICO

while both ends of the other set will be' tapered, so as to fail tooperate the switch.`

I claim as my invention- 1. A switch-fitting for a pneumatic-despatchsystem having a main-line passage and a branch passage leadingtherefrom, a switch mounted at said junction, a latch projecting intothe main-line passage, means for supporting said latch wherebyit maymove transversely from the passage or may move both longitudinally andtransversely from the passage, and an intermediate connection betweenthe latch and the switch which will swing the switch into the main-linepassage when the latch is moved simultaneously transversely andlongitudinally of the main-line passage.

2. A switch -fitting for a pneumatic-despatch systemhavinga main-linepassage and a branch passage leading therefrom, a switch mounted at thejunction of said passage, a shaft, anA arm carried by said shaft, alatch pivoted at one end to said arm and having its other endprojectable into the main-line passage, a guide permitting anindependent transverse withdrawal of the latch from the main-linepassage or compelling a combined' longitudinal and transverse Withdrawalof the latch with relation to the main-line passage, whereby saidmovement swings said shaft, and connections between said shaftandswitch.

3. A switch-fitting for a pneumatic-despatch system having a main-linepassage an d a branch passage leading therefrom, a switch mounted at thejunction of said passages, a shaft, an arm carried by said shaft, alatch pivoted at one end to said arm and having its other endprojectable into the main-line passage, a guide permitting anindependent transverse withdrawal of the latch from the main-linepassage or compelling a combined longitudinal and transverse withdrawalof the latch with relation to the main-line passage whereby saidmovement swings said shaft, connections between said shaft and switch, aplunger projectable into the mainline passage a car length behind thelatch, and intermediate connections between said plunger and said shaftfor projecting the plunger into the main-line passage when the shaft isswung.

4. A switch-fitting for a pneumatic-despatch-tube system, having themain-line passage 11, a branch 12, switch 13 pivotally mounted atthejunction,ashaft17carryingan arm 18, a latch 2O pivotally connected tosaid arm and having its other end projectable into the main-line passage11, guide 25 engaging a portion of the latch, and connections betweenshaft 17 and the switch, as and for the purpose set forth.

5. In a pneumatic-despatchtube system in which there is a junctionconsisting in part of a latch capable of substantially direct transverse`displacement and also capable of a switch-throwing movement which is acombined transverse and longitudinal withdrawal, acar having one endtapered to produce the first-mentioned movement of the latch and theother end blunt to produce the second-mentioned movement of the latch.

6. In a switch-itting for a pneumatic-despatch-tube system, thecombi/nationvith the switch-operating mechanism, of a plunger inclinedinward and rearward with relation tothe line of movement through thesystem, and connections between the switch inechan ism and plunger, forthe purpose set forth.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 6th day of December, A. D. 1902.
